VMware Workstation 4.5

You can save the current state of your virtual machine by suspending it. Later, you can resume the virtual machine to pick up work quickly, right where you stopped  with all documents you were working on open and all applications in the same state as they were at the time you suspended the virtual machine.

To suspend a virtual machine:

If your virtual machine is running in full screen mode, return to window mode by pressing the Ctrl-Alt key combination.

Click Suspend on the VMware Workstation toolbar.

When VMware Workstation has completed the suspend operation, it is safe to exit VMware Workstation.
